• US stocks fell on Tuesday after House Speaker Nancy Pelosi landed in Taiwan earlier in the day.
  • Investors continue to assess heightened tension between the US and China amid Pelosi's trip.
  • Taiwan is a key manufacturer of semiconductor chips that power everything from phones to cars.

US stocks were lower on Tuesday as investors continue to assess the rising tensions between the US and China following House Speaker Nancy Pelosi's trip to Taiwan.

As part of a broader trip to Asia, Pelosi landed in Taipei, Taiwan this morning, and the arrival of the number three US official has angered China considerably. China's military ran various military exercise drills and also conducted missile tests. 

China claims Taiwan as part of its territory and has said it would "not sit idly by" if such a senior ranking US politician visits the island. China has been seeking a "reunification" with Taiwan for decades.

Taiwan is a key manufacturer of semiconductor chips that power everything from phones to cars, and its untenable relationship with China is one reason why Congress passed the CHIPS act last month, a $280 billion package that incentivizes the onshoring of semiconductor manufacturing in America.
